image on tv goes green

I know the bulbs can fail and need to be replaced, but don't know what happens when one fails

You dont get a picture.

I have replaced ours 2x's now. According to the manual and what we have read in forums, they say that the picture quality will degrade as the bulb gets older. We have found this to be not true with our Sony xrd dlp...as the picture remains the same all the time and then one day------poof. No more tv.

Marty,
Try googling "Samsung DLP problem". I did this and got several results but didn't read the details but you may want to. I was having a green spot on my Sony lcd a few years ago and found out on a home theater forum this was a common problem. I called Sony support and they replaced the "color engine" at no cost, they came to my house and installed a new color engine to replace the bad one. It was like an unpublicized recall since you only received the replacement if you called and complained - not very proactive. I found out about this 'recall' by reading internet forums on my tv model. I'm not saying there's a similar recall on your model, just suggesting that you are more likely to find a resolution on other forums. Good luck.

When changing channels, the screen on my Pioneer sometimes goes to bright green. The sound is OK. At that point we have to turn it off and then back on. I asked Comcast about that and they said it's a fault of the HDMI connection with their cable box.

I have a 56' Samsung DLP around 6 yrs old. I have replaced the bulb, color wheel and light engine board in the last 14 months so I have some experience. Luckily, I had an extended 5 yr. warranty on to cover the board which runs around $1k for the part.. ...Bulbs can last 1000 to 3000 hrs depending on the type of use the unit gets. Bulbs begin in to flicker, take longer to turn on and have decreased brightness as they begin to fail...Your set is a DLP given its age not an LED. You say you replaced the bulb/wheel module.?? They are two separate items...One has nothing to do with the other...Bulbs run $80-$125. The color wheels run $150 and up and are not that simple to replace...If bulb was just replaced I would take a look at the wheel. I was able to replace mine with a little help from youtube and some folks on AVSforum.

Let me know

Raks,

Your problem sounds like a drop in the picture signal that causes the screen to go green. Could be the HDMI cord/connection or it could be a drop in the picture signal from the cable company. The audio signal may be strong enough that the audio doesn't drop out. Just a possibility.
